Central bank governors from across Africa are gathering at the 3i Africa Summit in Accra this week, with the complex challenge of integrating the continent's fragmented cross-border payments systems at the top of the agenda. The discussions come as regional economic integration under the African Continental Free Trade Area (AfCFTA) advances, creating an urgent need for more efficient and affordable financial flows between nations.

The scale of domestic payments infrastructure is already significant, as evidenced by South Africa's National Payment System. In 2024, the system processed a total of R164 trillion in transactions, according to data from the South African Reserve Bank. This figure underscores the maturity of certain national markets, but also highlights the contrast with the often cumbersome and costly processes for sending money between countries. The push for interoperability seeks to bridge this gap, allowing the continent's growing digital payment volumes to flow more freely across borders.

Central banks are seen as pivotal actors in this transition. A report from Currency Research notes that their role extends beyond regulation to actively shaping the instant payment system landscape, often by mandating interoperability between domestic schemes. "Central banks are increasingly taking a leading role in the payments ecosystem, not just as regulators but as catalysts for innovation and integration," the report states. This involves establishing common standards and legal frameworks to ensure security and trust in cross-border transactions.

Technological innovation, particularly in artificial intelligence, is expected to be a key enabler for this integration. Analysts suggest AI can help manage the complexities of multi-currency settlements, enhance fraud detection across different regulatory regimes, and improve the customer experience for cross-border transfers. The goal is to move beyond the current patchwork of bilateral agreements towards a more unified pan-African network.

The commercial imperative is clear. As intra-African trade grows, businesses and individuals demand payment solutions that are as seamless domestically as they are internationally. The dominance of large financial institutions in national systems, such as Standard Bank's processing of R164 trillion in payments in the 2024 financial year, indicates where much of the transaction volume originates. Integrating these robust domestic networks is viewed as a more practical path than building entirely new cross-border infrastructure from scratch.

However, significant hurdles remain. Divergent regulatory approaches, varying levels of digital infrastructure development, and concerns over monetary policy sovereignty are frequent points of discussion among policymakers. The summit provides a forum for aligning these differing national priorities with the broader continental ambition of the AfCFTA, making the dialogue among central bank governors a critical step toward a more financially integrated Africa.
